Exodus 5 begins with a visit to Pharaoh to inform him of what the Lord has said, but Pharaoh did not listen to Moses and Aaron, saying “Who is the Lord, that I should obey him and let Israel go? I do not know the Lord and I will not let Israel go.” Pharaoh then blamed Moses and Aaron for trying to take the people away from their labor, so he ordered the slave drivers to be more harsh and increase their labor. Moses returned to the Lord and said, “O Lord, why have you brought trouble upon the people?” and Moses complained to God that he had not rescued the people.
